Advantage of features for upgrading from 2 to 3

Hi
I have a ISPconfig 2 instance, which is running fine. Now may be I may go for ISPConfig3 installation, all my present needs are meet by ipconfig 2. In this case what should be main advantage in moving to ISConfig 3 in terms of features.
Guidance requested
Thanks

ISPConfig 2 is not under development anymore and can not be installed on latest Debian distributions as the apache 1 which is bundled with ispconfig 2 does not compile with latest glib libraries. I wont install ispconfig 2 on a new server as this version is end of life for more then a year now, so neither bugs nor possible security issues will get fixed anymore.

ISPConfig 3 has many improved if you compare it with ispconfig 2: much more features, speed, scalability, maintenance, more and faster php modes, better mail scanning etc.
